Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing a member for a top plate with an aquarium. The present invention provides a new manufacturing method when attaching to a composite member formed by adhering to a material. The effect of the present invention is that it is possible to obtain a top plate with an aquarium that has excellent design, good water drainage, is easy to manufacture, and is highly economical. FIG. 3 is a partially enlarged cross-sectional view of the thus obtained member for a top plate with a water tank.

[Conventional technology]

As a conventional technique for manufacturing a top plate with a water tank, for example, there is an invention disclosed in Japanese Patent Publication No. 57-34413. In this application, first, as shown in the perspective view of FIG. 2, a core material (B) in which a hole (A) for fitting a water tank is formed is adhered to a decorative board (C). Next, as shown in partially enlarged sectional views from a to e in FIG. 3, a reinforcing urethane resin layer (E) is injected onto the back side of the decorative board in the fitting hole (A), and after curing, the resin layer (E) and the decorative board (C) are bonded together. Simultaneously cut to match the shape of the flange to the water tank to form the opening end face of the top plate. Furthermore, after smoothing the back side of the reinforcing urethane resin layer, the flange part of the aquarium is brought into contact with the flange part, and the flange part is crimped to the reinforcing resin layer using the mounting bracket. The aquarium was attached to the top plate by injecting and hardening a urethane resin layer for filling and adhesion into the recess surrounded by the open end surface of the material.

[Problem that the invention seeks to solve]

According to the manufacturing method using the conventional technology, the reinforcing urethane resin layer (E) formed on the back side of the decorative board requires a cutting process with a knife after it hardens. Since it is crimped with a metal fitting, it needs to be strong enough to withstand this crimping strength. Therefore, the thickness of the reinforcing resin layer is approximately 5 mm.
10 mm, which caused a significant deterioration in appearance. In addition, manufacturing requires at least two cutting processes: one to form the hole for fitting the water tank into the core material, and the other to form the top plate opening after the reinforcing urethane resin is injected and hardened. This method has the disadvantage that the manufacturing process is complicated and economical efficiency is low. In addition, since a second cutting process is performed after the reinforcing urethane resin layer E has hardened, this manufacturing method is not only unsuitable for assembly-line continuous production. Since the hole for fitting the water tank is determined at the time of cutting and forming the hole in the material, there is no flexibility in the position of the water tank, which is inconvenient.

The present invention solves the above-mentioned conventional drawbacks, and in summary, when forming an opening in a composite member made by adhering a thermosetting resin decorative board with a thickness of 2 mm or more to a wood base material, the above-mentioned problems are solved. The wooden base material of the composite member is made of wood according to the size of the aquarium so that the open end of the wooden base material is larger than the outer peripheral end of the aquarium flange part, and the open end of the decorative board is smaller than the outer peripheral end of the aquarium flange part. The system base material and the thermosetting resin decorative board are cut, and a waterproof and adhesive sealant is applied to the back of the protruding part of the thermosetting resin decorative board, and the aquarium flange is brought into contact with the aquarium mount. The present invention provides a novel method for manufacturing a ceiling member with an aquarium, characterized in that the aquarium is attached by screwing the aquarium from the back surface of the open end of a wooden base material.

[Means for solving problems, their effects and examples]

Embodiments of the present invention will be specifically described below based on the drawings. First, FIG. 1 shows a partially enlarged sectional view of a member for a top plate with a water tank manufactured by the manufacturing method of the present invention. The member for the top plate with an aquarium shown in this figure is a thermosetting resin decorative plate cut into an opening 3 of a composite member made by pasting a thermosetting resin decorative board 1 with a thickness of 2 mm or more to a wood base material 2. An aquarium flange 6 is crimped onto the back surface of the plate protrusion 4 via a waterproof and adhesive sealant 5, and an aquarium mount 7 is screwed onto the aquarium 8 to attach the aquarium 8.

Next, a to e in FIG. 4 are partially enlarged cross-sectional views of a process diagram showing an embodiment of the method for manufacturing a member for a top plate with an aquarium according to the present invention, and a to e in FIG. It shows a perspective view of a part of the back side of the figure. In this manufacturing method, first, a melamine resin decorative board 9 with a thickness of 3 mm is pasted on a plywood base material 10, and then a rotary blade such as a router is used to attach the flange portion 1 of the aquarium 11.
2, the open end 13 of the plywood base material is larger than the outer peripheral end 14 of the aquarium flange part, and the open end 15 of the melamine resin decorative board is smaller than the outer peripheral end 14 of the aquarium flange part. Then, the base material and the decorative board are cut into an annular shape to form an opening 17 for attaching an aquarium having a protrusion 16 of the melamine resin decorative board. Next, after applying a silicone resin sealant 18 to the back surface of the decorative board protrusion 16 and bringing the flange 12 of the aquarium into contact with it, use the L-shaped aquarium mounting bracket 19 to attach the open end back surface 20 of the plywood base material.
Attach the aquarium 11 by screwing it in with wood screws 21. Next, by wiping off the silicone resin sealant protruding portion 22 on the open end 15 side of the decorative board with a cloth, a member for a top plate with an aquarium according to the manufacturing method of the present invention is obtained. Next, FIGS. 6a and 6b are partially enlarged cross-sectional views showing a part of a process diagram which is an embodiment of another manufacturing method according to the present invention, and FIG.
After attaching the aquarium 11 with the L-shaped aquarium mounting bracket 19 using wood screws 21 as explained in the figure,
It is characterized in that urethane resin 24 is injected into a recess 23 surrounded by the back side of the water tank 11 and the open end 13 of the plywood base material 10 and hardened. Next, FIG. 7 shows a perspective view of an example of a member for a top plate with a water tank obtained by the manufacturing method of the present invention. A water tank 11 is attached directly below the open end 15 of the decorative resin board with a thin layer of silicone resin sealant 18 interposed therebetween.

〔Effect of the invention〕

As described above, according to the method of manufacturing a member for a top plate with a water tank of the present invention, first, regarding the mounting position of the water tank, an opening is formed in advance at a predetermined position of the core material as in the conventional example. Rather, the opening 17 for attaching the water tank 11 is formed at an arbitrary position in the composite member made by pasting the melamine resin decorative board 9 with a thickness of 3 mm and the plywood base material 10, so the mounting position of the water tank is fixed. It has the advantage of being freely configurable. Next, the greatest feature of the manufacturing method of the present invention is that when forming the opening in the composite member, the decorative board and the plywood base material are pasted together and then cut. Therefore, the cutting process only needs to be completed once, and compared to conventional manufacturing methods, this method has the advantage of greatly improving productivity and being economically efficient. Furthermore, according to the manufacturing method of the present invention, almost only the thickness of the decorative board is exposed on the open end surface of the top plate member, which is extremely thin and has a good design compared to conventional products, which have a thickness of 5 mm to 10 mm. It has the advantage of being excellent. Furthermore, since the manufacturing method of the present invention is characterized in that a thermosetting resin decorative board with a thickness of 2 mm or more is used as the surface decorative material, a reinforcing urethane resin layer is added to the back side of the decorative board like conventional products in order to have excellent bending strength. There is no need to form. Therefore, it has the great effect of simplifying the manufacturing process. In addition, there is a waterproof and adhesive sealant between the thermosetting resin decorative board and the flange of the aquarium, and since the aquarium is located below the surface of the top plate, it is difficult to close the water tank. This has the advantage of being excellent in terms of performance.

In addition, the thermosetting resin decorative board referred to in the present invention includes melamine resin decorative board, dap resin decorative board, polyester resin decorative board, etc., as well as metal foil such as stainless steel foil and aluminum foil and thermosetting resin impregnated prepreg. Includes hot-press molded metal foil decorative board. Further, the thickness of the thermosetting resin decorative board is set to 2 mm or more according to the manufacturing method of the present invention, in which an opening is formed in the composite member, and the flange of the aquarium is brought into contact with the back surface of the protruding part of the decorative board. This is because the water tank is pressed onto the back surface of the decorative laminate projection from the back surface of the flange portion, so the flexural strength of the decorative laminate is required. That is, if the thermosetting resin decorative board is thin, when the aquarium is attached using the aquarium mounting tool, the decorative board cannot withstand the tightening force of the wood screws and the protruding portion of the decorative board is lifted above the top plate. Therefore, the thermosetting resin decorative board requires a thickness of 2 mm or more, and the thickness is 2.5 mm to 5 mm.
It is desirable that it is around mm. Next, the wood base material refers to plywood, particle board, fiber board, etc. Furthermore, when forming an opening by cutting the composite member made by pasting the decorative board and the wood base material, the opening dimension of the thermosetting resin decorative board is smaller than the outer peripheral end of the aquarium flange part, and The size of the opening in the wood base material is cut to be larger than the outer peripheral edge of the aquarium flange. FIG. 8 shows a partially enlarged sectional view of another member for a top plate with an aquarium produced by the manufacturing method of the present invention, in which the decorative material is applied to a composite member consisting of a 5 mm thick melamine resin decorative board 25 and a plywood base material 10. The open end 15 of the board is smaller than the outer circumferential edge 14 of the aquarium flange portion and the inner circumferential edge 26 of the aquarium flange portion, and the open end 13 of the plywood base material is larger than the outer circumferential edge 14 of the aquarium flange portion. It is formed by cutting. Next, the means for cutting the decorative board and the plywood base material is not limited, but it is preferable to use a rotary cutter such as a router machine to cut the decorative board and the plywood base material at once. FIG. 9 is a perspective view showing an embodiment of the rotary cutter used in the present invention, which consists of a large-diameter base 27 and a small-diameter base 28, and a cutter tip 2 is attached to the end of this base.
9 and has a rotating shaft 30 at the center. In addition, the water tank referred to in the present invention refers to, for example, a sink for a sink or a wash bowl attached to a sink or a washstand, and the shape and material thereof are not limited in any way, and may include stainless steel, iron plate enamel, etc. In addition to metal aquariums such as those made of stainless steel enamel, ceramic aquariums and synthetic resin aquariums are also included. Next, as the sealant having waterproof and adhesive properties, for example, a silicone resin filler is most suitable. The material and shape of the aquarium mount are not particularly limited; for example, it may be an L-shaped metal aquarium mount 31 as shown in FIG. 10, or a metal flat plate 32 as shown in FIG. and wood 33 may be combined. The thermosetting resin for injection used in the present invention is, for example, a synthetic resin such as polyurethane, polyester, or epoxy.

As explained above, according to the method of manufacturing a member for a top plate with an aquarium of the present invention, an opening is formed at an arbitrary position of a composite member formed by pasting a thermosetting resin decorative board and a wood base material. Since it is formed by cutting in one set, it has the advantage of being highly flexible in the mounting position of the aquarium, as well as being highly productive and economical. Further, since almost only the thickness of the decorative board is exposed on the open end surface of the top plate member, it has the advantage of being thin and having an excellent appearance. Furthermore, in the manufacturing method of the present invention, a waterproof and adhesive sealant is applied to the back surface of the protruding part of the thermosetting resin decorative board at the opening, and the flange of the aquarium is brought into contact with the aquarium, and then the aquarium is fixed using an aquarium mounting tool. Since it is crimped and fixed, it has the advantage of being excellent in water closing, and since it is not necessary to form a reinforcing resin layer as in the conventional case, it is easy to manufacture and is extremely useful in practice.
